Master Fic List contemplation.... worth the effort?

I've noted a few folks here have cobbled up a 'Master List' with links to all of their fics, and while I've enjoyed clicking around on them I really can't decide if it's worth the time and effort to do one myself. I mean, well - first of all there's so darn much of it and it would take a bit of doing... and secondly isn't it well enough served via the author searches at ff.net, Stories of Arda and Teaspoon? Hm.

Am I just contemplating giving up several hours to reinvent the wheel?

Those of you with lists for your fic, have you found them to be useful? Or was it 'meh, whatever' in the long run?
